gshhgtograss − Extracting GSHHS and WDBII data in GRASS-compatible ASCII format
gshhgtograss −i gshhs_[f|h|i|l|c].b [ −xminx ] [−Xmaxx ] [ −yminy ] [ −Ymaxy ]
gshhgtograss
reads the binary coastline (GSHHS) or binary river/border
(WDBII) and and translates it into an ASCII format suitable
for import into GRASS. It automatically handles
byte-swabbing between different architectures.
gshhs_[f|h|i|l|c].b
One of the GSHHG binary data file as distributed with the GSHHG data supplement. Any of the 5 standard resolutions (full, high, intermediate, low, crude) can be used. The resulting files are called dig_[ascii|att|cats].gshhs_[f|h|i|l|c].
